Answer:
- Substitute $410 for C in the equation and solve.
- 9 people could go on the trip with $410
Step-by-step explanation:
B) We are told the bus company is charging them using the formula;
C = 50 + 40n
Where;
C is the total cost
n is the number of people
Now, we are told that a parent group is willing to give the club $410. Thus, we will substitute $410 for C in the equation and solve.
410 = 50 + 40n
Subtract 50 from both sides to get;
410 - 50 = 40n
360 = 40n
n = 360/40
n = 9
Answer:
Step-by-step explanation:
total surface area=3×(1/2×10×6.7)+1/2×10×8.7=3×(33.5)+43.5
=100.5+43.5
=144
He is left with 12
1/5 of 10 is 2 so he was left with 8
2*2 is 4, and 8+4 is 12!
The length of AC is 126 units.
Answer:
8x+6y=48
x+y=7
multiply bottom equation by 6:
8x+6y=48
6x+6y=42
subtract equations:
2x=6
divide 6 by 2:
x=3
therefore:
y=4
